PRINTING OE FABRICS -AND ARTICLES.

No Drawing.

The success of this invention is rather surprising inasmuch as, for instance, it was expected that by treating a fabric like velvet, containin cellulose acetate sllk m xed with cotton with a solvent for cellulose acetate, a film would; be obtained which sticks.

tothecotton fibre without possibility of remixed fabric (for. instance a fabricwith a cotton war and a mixed fillingiconsisting of alternatively two threads of cellulose acetate and twothreads of cotton) I print, according to the well-known method. or according to any othermet-ho-d' a thoroughly mixed paste, consisting of 30 parts lactic acid, 3 parts water, 5 partsdextrin and 12 parts infusorial earth on the fabric containmg the celluloseacetate silk. The "rinting ofthis paste can. be made on OIIQSldQ-Of the fabric or on both sides ofthe fabric. Then the-fabric so printed is. exposed in any appropriate fashion to a temperature, for instance, of to 125 Cruntil the moment a sample of the cloth so printed and treated shows that by washin with water the cellulose acetate silk has been entirely removed at the spot where the pr nting took place. i 4

This invention canbe worked outwith the very well-known. apparati of discharge printin but the invention isnot 1imitedrto that an may be usedin any device which is able to get the result.

The roportions of the paste can varied in a wide range andinsteadof lactic cold or other solvents of cellulose acetate,vlike acetic acid, acetone or higher boiling point solvents or any other suitable solvent or com-- bination of solvents of acetate of cellulose can be used. Instead of dextrin any other suitable thickening agent can be used, for instance, starch, casein, etc., just as well as in-.

fusorial earth can be re laced by other suit able powdered materia s such as blotting paper, powdered cellulose, barium sulphate or any other solid absorbent material in powdered form which has no chemical effect on the solvent used; for example if instead of lactic acid, acetone or another neutral solvent is used, powdered calcium or barium carbonate can be used.

This invention is not limited to cellulose acetate silk but also applies to the discharge Application filed September 20, 199. Serial No. 738,947.

printing of mixed fabrics, like velvets or a other fabrics or articles containing artificial silks made of cellulose esters, like cellulose butyrate, cellulose propionate, -nitr0cellulose silk and so forth; in other words, it applies to silk made .outv of organic or inorganic esters of cellulose, as well as of ethers of cellulose, such as cellulose ethylate, methylate,

-benzoylate, etc.

By this invention for instance beautiful jacquard. effects are obtained on mixed fab- "IICS (consisting partly ofcellulose acetate silk and partly of other fibres or on velvets having, for instance, a backof cotton or silk or wool or mixtures of different fibres, whilst the face of the velvet consists ofcel-' lulose acetate silk) This invention is also applicable to fab rics, velvets or articles consisting entirely of cellulose acetate or cellulose ester or cellulose ether silk or mixturesof these silks and I the fabrics so obtained with stamped out patterns inagreement with this invention can be largely used under others for the manufacture of novelties and fancy articles in the dress goods trade.

The cellulose acetate silk or cellulose ester silk or cellulose ether silk inthe fabrics can according to wish be partly or totally removed according to the above invention.

What I claim is:

14 A process for the printing of mixedv fabrics containing fibers of a cellulose derivative consisting in applying to portions of the fabric the mixture of a solvent for the cellulose derivative an inert powder and a thickening agent, allowing this mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose derivative fibers are removable .by washing with water.

2. A process, for the printing of mixed fabrics containing fibers of a cellulose derivative consisting in up lying to ortions of the fabric a mixture 0 lactic aci an inert powder and a thickening agent, allowing the mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose deriva tive fibers are removable by washing with water.

3. A process for the printing of mixed fabricscontaining fibers of a cellulose de rivative consisting in applying to portions of the fabric a mixture of 12 parts of infusorial earth, 5 parts dextrin, parts lactic acid and 3 parts water, allowing this mixture to remain in contact with the fabric at a temperature below 125 C. until at. least a part of the cellulose derivative fibers are removable by washing with water.

4. A process for the printing of mixed fabrics containing fibers of an organic cellulose derivative consisting in applying to portions of the fabric a mixture of a solvent .for the organic cellulose derivative, an inert powder and a thickening agent, allowing this mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the organic cellulose derivative fibers are removable by washing 5 fabrics containing fibers of a cellulose ester consisting in applying to portions of the fabric the mixture of a solvent for the cellulose derivative, an inert powder and a thickening agent, allowing tiis mixtureto remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose ester fibers are removable by washing with water.

7. A process for the printin of mixed fabrics containing fibers of a ce lulose ester consisting in applyin to portions of the fabric a. mixture of lactic acid, an inert powder and a thickening agent, allowing the mixture to remain in contact with the fabric at a temperature below 125 C. until at least a )art ofthe cellulose ester fibers are removable by washing with water.

8. A process for the printing of mixed fabrics containing fibers of a cellulose ester consisting in applying to portions ofthe fabric a mixture of 12 parts of infusorial earth, parts dextrin, 30 parts lactic acid and 3 parts water, allowing this mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose ester fibers arc removable by washing with water.

9. A process for the printing of mixed fabrics containing fibers of a cellulose acetate consisting in applying to portions of the fabric the mixture of a solvent for the cellulose derivative, an inert powder and a thickening agent, allowing this mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose acetate fibers are removable by washing with water.

10. A process for the printing of mixed fabrics containing fibers of cellulose acetate consisting in applying to portions of the fabric a mixture of lactic acid, an inert powder and a thickening agent, allowing the mixture to remain in contact with the fabric at a temperature below 125 C. until at least a part of the cellulose acetate fibers are removable by washing with water. i

11. A process for the printing of mixed fabrics containing fibers of cellulose acetate consisting in applying to portions of the fabric a mixture of 12 parts of infusorial earth, 5 parts dextrin, 30 parts lactic acid and 3 parts water, allowing this mixture to remain in contact with the fabric at a temperature below 125 G.-until at least a part of the cellulose acetate fibers are removable by washing with Water.

In testimony whereof, I have hereunto subscribedmy name.
